Thanks for the advice David

I knew "higher" was required given the obvious failure of my "lower" experiment but wasn't sure how much.
Cheers,

The 2.2 & 2.5bar settings in the manual are both cold pressure, the 2.5bar being with the car at full load.
When using normal road tyres on the track the normal practice is to raise the pressures.
If you take the std full load cold pressure of 2.5bar and add the 0.3bar stated in the manual for sustained high speed use you get 2.8bar as the maximum cold pressure.
On no account run lower than 2.2bar cold pressure because you will either pull the tyres off of the rims or you will overheat the sidewalls and get a blowout.
I'd say 2.5bar cold would be a good place to start.
